VkPhysicalDeviceFragmentDensityMapFeaturesEXT

The VkPhysicalDeviceFragmentDensityMapFeaturesEXT structure is defined as:

typedef struct VkPhysicalDeviceFragmentDensityMapFeaturesEXT {
    VkStructureType sType;
    void* pNext;
    VkBool32 fragmentDensityMap;
    VkBool32 fragmentDensityMapDynamic;
    VkBool32 fragmentDensityMapNonSubsampledImages;
} VkPhysicalDeviceFragmentDensityMapFeaturesEXT;

This structure describes the following features:

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• fragmentDensityMap specifies whether the implementation supports render passes with a fragment density map attachment. If this feature is not enabled and the pNext chain of VkRenderPassCreateInfo includes a VkRenderPassFragmentDensityMapCreateInfoEXT structure, fragmentDensityMapAttachment must be VK_ATTACHMENT_UNUSED.
• fragmentDensityMapDynamic specifies whether the implementation supports dynamic fragment density map image views. If this feature is not enabled, VK_IMAGE_VIEW_CREATE_FRAGMENT_DENSITY_MAP_DYNAMIC_BIT_EXT must not be included in VkImageViewCreateInfo::flags.
• fragmentDensityMapNonSubsampledImages specifies whether the implementation supports regular non-subsampled image attachments with fragment density map render passes. If this feature is not enabled, render passes with a fragment density map attachment must only have subsampled attachments bound.

If the VkPhysicalDeviceFragmentDensityMapFeaturesEXT structure is included in the pNext chain of the VkPhysicalDeviceFeatures2 structure passed to vkGetPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. VkPhysicalDeviceFragmentDensityMapFeaturesEXT can also be used in the pNext chain of VkDeviceCreateInfo to selectively enable these features.
